Notes: Some installs require changing of A/C, P/S, and Alternator Brackets depending on engine choice. Headers also may have limited options.

Motor and Transmission combos can vary greatly on where the transmission will sit. Powerglides, T350, and T200s have roughly the same distance from housing to mount. Most others with exception to the 4L80 will fall in the range of the 700R4. Please know what transmission you are using when selecting your motor mount combination.

  1. Chassis frame kit

    Posted by Jason on 15th Dec 2021

    Quality product. Fit and finish is nice. Can’t wait to get it installed and see the finished results. Thanks

  2. Product Great, Packaging not so much.

    Posted by CL Fairbanks on 24th Nov 2021

    This is a well designed and produced product, The packaging however is not as good. Heavy steel parts with precisely cut edges may need a little stronger boxes. Some of the boxes were crushed and had holes in them. Two of the packing lists were almost destroyed and I was missing two parts. 504 sent those parts after one phone call. I have and will continue to suggest this product to friends . I have only just started my mock up ( due to surgery) however from what I see I am going to be very happy with my 504 frame swap kit.

  3. Ready to install ‘54 body...

    Posted by Scott Stanfield on 15th May 2021

    This kit is impressive. The pieces are stout and the instructions are straight forward. My frame is a 2002 s10 and required a few deviations, but staff quickly answered any questions I had. I’m using the stock 4.3l and AT. As of writing this review, all the pieces have been installed. This review will be updated after the ‘54 body is installed.

  4. Well made. Simple and to the point.

    Posted by Phil on 12th May 2021

    I had no problem assembling the kit. Came with a great instruction manual.

  6. s10 conversion

    Posted by PETER MCNERNEY on 19th Feb 2020

    it was easy and straight forward to install. instructions were clear. i would like to see you guy make a batteries frame notchout kit for the s10 so we could put the battery in original location on a 47-55. im fabing my own it should be pretty easy but would be better if you guys engineered it an cnc the pieces. thanks

    This company is fantastic to work with. Very impressed with the packaging, parts, lables, and instruction booklet. With the detailed instructions, just about anyone could assemble all these brackets. I liked the fact that they have a customer service number to call if you need help, and honestly I thought I would be calling several times. I havent needed to call once. If you are even slightly debating on going this route, it is well worth the money!
