Air Cooled Engineering is on of the first places that I look when buying a crankcase.   RIMCO in Southern California is another.If you are building an engine from scratch, then step one should be to consider purchasing a crankcase from a machine shop that specializes in air-cooled Volkswagens.   The crankcase is after all is said and done the foundation for your engine. Like most of my listings, A.C.E works normal Monday through Friday business hours.   They don't have a razzle, dazzle web catalog.   So, you'll need to contact them by phone. Mailing address and telephone: 360 W. 6100 South, #A - Salt Lake City, UT. 84107. 1 (801) 943-1234 Aircooled.net is the first place that I look when buying Type 1 engine components.   ACN is definitely the place to go to for carburetors, because someone there definitely knows the ins and outs of proper VW carburetion.. Take note that the business address for ACN is next door to Air Cooled Engineering. The business philososphy of ACN centers around customer service and to avoid selling many of the crap aftermarket products that other vendors will gladly sell you. - You pay a bit more at Aircooled.net, but avoid hassling with crap parts that don't fit well and have a high failure rate. - If you are building an engine for your VW Bus and reliability is important, this is your safest VW parts source. Furthermore, if they have your part in stock - and - you needed it to arrive yesterday, Aircooled is your best bet, once again.

Airhead Parts  offers a selection of Type 2 parts from European sources - in addition to many stock replacement parts for a Type 1 Beetle and 141 Ghia.   I like the way the web site lists which parts are of Brazillian or German origin.   Not all parts are from Brazil or Europe.   Some are labeled simply as reproduction. A couple of things Airhead Parts offers that is uncommon.   After your first order, expect a professional, color catalog in mail, printed on glossy paper, which I like receiving.   Their web site also contains a help forum.   If you own a Beetle or a Ghia, check out their Hi-Def videos in the tech section. They also still use the original VW part numbers for most items.

Many rebuilt parts, to include do-it-yourself ball joint replacement.   Not the least expensive, but high quality supplier of hard to find VW bus parts.   This a small friendly operation that knows Buses. The first thing I like about Bus Boys is that the same person has been taking my orders for the past 15 years and knows what the differences are on a 1971 VW Bus from a 69'er - unlike the 24/7 Big Box operations elsewhere that ordering operations to a subcontractor. The second thing I like is they still use the original VW part numbers for most items.

Products vary, one year to the next.   This year it may be your only source for N.O.S. German heater boxes.   While next year it may be for those wonderful Brazilian rearview mirrors.   Be advised that their packing for shipping is sloppy - So order heavier parts separately.   Also, their lead time upon ordering is about 2 - 3 weeks to your door - which indicates they do a lot of drop shipping from other vendors. I use them for body parts and difficult to source items. Mailing address and telephone: 4801 Gravel Pike - Perkiomenville, Pa.

Note: Chinese parts don't always fit properly and more often than not will need to be replaced sooner rather than later. Definitely a big box operation.
